I want to know that whether we can use NodeMCU instead of Bolt device to get all these freedom of using these tools because I have not received the delivery package yet due to the lockdown procedures
Bolt has its customized library and packages. You would also not be able to use the bolt cloud feature using a nodemcu as it requires an API key. Therefore yes you can do all this only if you can code everything from scratch that is even receiving and processing the data as bolt cloud would not available to use otherwise irs better to use the bolt module it’s woth waiting. Warm regards!!
